4 Claims.

This invention relates to coin-controlled dispensing machines and moreparticularly to the means for handling the coin which is inserted torelease the dispensing mechanism, so that the coin will be delivered tothe money box, if the package which is purchased is delivered, or willbe returned to the purchaser if the package is not delivered, as,obviously, either the package must be delivered or the coin must bereturned.v

Difiiculty has been encountered in machines of this type, in that it hasbeen discovered that by pulling out and then pushing back the operatinghandle very quickly the package will not only be delivered, but the coinwould be returned.

The primary object of my invention is to provide a construction forhandling the coin in which the coin will be retained if the package isdelivered regardless of whether the operating means is operated quickly,or at normal speed.

As the means for retaining or for returning the coin must be operatedduring the time in which the operating device is moved from and,returned to its initial position, I have accomplished this object byproviding means for retarding the operation of the coin returning means,so that it may not be operated until after the operating device has beenreturned to initial position, whereby the coin retaining means, which isoperated by the package when it is dispensed, will have ample time tooperate before the coin returning means can operate.

For a more complete disclosure of the specific means which I employ,reference is now made to the following specification, in connection withthe accompanying drawings, in which:

Fig. 1 is a side elevation of the coin handling mechanism which isemployed.

Fig. 2 is a detail sectional view taken at line 2-2 of Fig. 1.

Fig. 3 is a similar View showing some of the parts in a differentposition.

Fig. 4 is a detail sectional view at line 4-4 of Fig. 1.

Fig. 5 is a view similar to Fig. 1, showing certain parts in differentpositions.

Fig. 6 is a detail view of a portion of the coin retaining and coinreturning means.

As shown in the drawings, the main operating device consists of astraight bar Iii having a handle at its outer end and a series of gearteeth on its top side arranged in mesh with a gear l2 on the shaft M. Awheel I6 is mounted on said shaft, and a bell crank lever I8 is pivotedat It, and one end thereof is engaged in a notch 26 in wheel I6. Theopposite end of said lever has a shoulder 2| which is arranged to engagea shoulv der 22 on a locking lever 24, so that if no coin has beeninserted and the bar It] is pulled out, the parts immediately becomelocked.

If a coin has been inserted and passes the coin testing means, it willlodge on support 25, in the position indicated at X in Figs. 1 and 6, sothat, as lever I8 is advanced, it will push the coin against lever 24and lift it out of locking position, permitting the dispensing operationto be performed.

By this movement the coin is advanced to the position indicated at y, inFigs. 1 and 6, in which position it is supported by two pivoted dogs 26and 28 directly over a vertical partition 30, which separates the coinretaining passage 32 and the coin returning passage 33. When in thisposition if dog 26 is moved so that it is withdrawn from its coinsupporting position, the coin will fall into the passage 32 and passinto the money box, and if the dog 28 is moved, so that it is Withdrawnfrom its coin supporting position, the coin will be returned.

It may be assumed that the package dispensing operation will beperformed when the bar It] has been pulled out to its fullest extent andthat a package will be discharged into a passage 34 at the rear side ofthe machine. Means are provided for operating the dog 26 when a packageis discharged into said passage, which consist of a 30 shelf 35, whichis pivotally mounted on a shaft 36, and is normally supported in ahorizontal position in passage 34 by means of a counterweight 31. Alever 38 is pivoted at 39, and one end of said lever is arranged inengagement with a lug 56 on counterweight 31 and the opposite end ofsaid lever is pivotally connected at 4! to an arm 62 mounted on a shaft43. In some instances a second shelf 44, indicated in dotted lines inFig. 1, is mounted at shaft 43, and is normally held ina horizontalposition by counterweight 31, through the action of lever 38. A stiffwire 45 is connected to pivot 4| at end of arm 42, and is exline to thedotted line position of Fig. 5,.thereby pulling wire 45 rearwardly andswinging dog 26 sufficiently to withdraw it from its coin supportingposition, so that the coin will fall into the money box. The same actionwill take place if the shelf 44 is swung downward by a package 5 closedat the opposite end, except for a leak hole the size of which isregulated by a screw valve 50. A collar 5| is secured on rod 41 and aspring 52 is connected thereto and to the cylinder, and normally acts tohold the rod in .the position of Figs. 1 and 2. A collar "54 "is alsomounted on rod 41, in position to engage one end of dog 28, as shown inFig. 2. As thus arranged, spring 52 normally holds the parts in theposition of Fig. 2, in which position the dog 28 is held in aninoperative position. The lever I18 has a projecting lug 55, so arrangedthat, when the lever is moved from its normal position, after a coin hasbeen inserted, the lug 55 engages collar 5| and pushes rod 41in thedirection to withdraw it from'cylinder 49, .and thereby moves collar 54out of 'engagement with one arm of dogz28 and into en- ;gagementwith'the-otherQarm thereof, thereby moving the dog into its operative,or coin supporting position, as shown in Fig. 3, so that, when the coinis discharged from support 25, it will be intercepted by the dogs 1326and 12-8 and held iniposition 1110f Fig. 6. Ifdog 26 is operated by the'falling package, the coin will be retained as before described, but ifno package is delivered the .coin will be retained in positiony untilthe lever I8 is returned to normal position and the return of rod 4'l tonormal position is permitted. The return movement of rod 41 is, however,retarded by thepiston "48, the speed at which it is returned dependingon-the adjustment of valve '50, which permits the air to escape slowlyfrom cylinder 49, so that if the operating bar In is pulled out andpushed back quickly, the shelves 36 or 44 will have ample time tooperate-dog 26 and discharge the coin into the money-box, before the dog28 is movedtor'its inoperative position, and this may occur some timeafter the operating bar has been returned to initial position.

If no package is discharged, when the rod' 4! is moved back to itsinitial position, the dog 28 will be moved' to its inoperative positionpermitting the coin to be returned. I

With the above described arrangement it will not be possible to securethe package and the return of the, coin by pulling out and pushing backthe operating bar very quickly, as the package 'will have ample time tofall and operate the do 26 before the rod 41 will be permitted by thedash pot to move'back sufliciently to operate the dog 28.
